Measured Mass‐Loss Rates of Solar‐like Stars as a Function of Age and Activity
TL;DR: In this article, the mass loss per unit face area is correlated with X-ray surface flux, and a power-law relation is derived for the solar-like GK dwarfs, showing that the solar wind may have been as much as 1000 times more massive in the distant past.

Absolute Dimensions of the M-Type Eclipsing Binary YY Geminorum (Castor C): A Challenge to Evolutionary Models in the Lower Main Sequence*
TL;DR: In this article, the authors presented spectroscopic observations of the double-lined eclipsing binary YY Geminorum (P = 0.814 day), a member of the Castor sextuple system and one of the benchmarks for the comparison between observations and stellar evolution theory in the lower main sequence.

Constraints on the Geometry of Circumstellar Envelopes: Optical Interferometric and Spectropolarimetric Observations of Seven Be Stars
Andreas Quirrenbach,Andreas Quirrenbach,Karen S. Bjorkman,Karen S. Bjorkman,J. E. Bjorkman,J. E. Bjorkman,Christian A. Hummel,David F. Buscher,David F. Buscher,J. T. Armstrong,David Mozurkewich,N. M. Elias,Brian Babler +12 more
TL;DR: In this article, the authors obtained contemporaneous optical interferometry and spectropolarimetry of seven Be stars and showed that the envelopes of four of them were not circularly symmetric and showed clear evidence of elongation.

Stellar Lyα Emission Lines in the Hubble Space Telescope Archive: Intrinsic Line Fluxes and Absorption from the Heliosphere and Astrospheres*
Brian E. Wood,Seth Redfield,Jeffrey L. Linsky,Hans-Reinhard Müller,Hans-Reinhard Müller,Gary P. Zank +5 more
TL;DR: In this paper, the authors search the Hubble Space Telescope (HST) archive for previously unanalyzed observations of stellar H I Lyα emission lines, their primary purpose being to look for new detections of Lyα absorption from the outer heliosphere and to also search for analogous absorption of the astrospheres surrounding the observed stars.

TL;DR: In this article, a survey of nearby, main-sequence A-, F-, and G-type stars with the CHARA Array was performed, successfully measuring the angular diameters of forty-four stars with an average precision of ~1.5%.
